べく

べく is a classical/dated Japanese expression used to indicate purpose or intention, similar to “in order to” or “for the sake of” in modern Japanese, but with a literary or formal nuance. It often appears in written prose, literary works, or formal speeches. It tends to emphasize deliberate, purposeful action toward a specific goal and can carry a tone that is earnest, solemn, or slightly old-fashioned. The typical pattern attaches to the verb’s base in classical conjugation, and it is less common in casual everyday speech. When used with nouns or adjectives, it can indicate motive or aim behind an action or state.
